H23 hydrophones
Small, self-amplified, shielded hydrophones for underwater acoustic measurement from 5 Hz to 150 kHz, rated to 680 m depth.
Description
The H23 series hydrophones are small, versatile, self-amplified and shielded sensors for underwater acoustic test and measurement. Three models (H23-080, H23-100 and H23-130) cover different sensitivities and frequency ranges.
Key features
- Wide, flat, omnidirectional frequency response
- Operation to 680 m sea water depth (1000 PSI)
- Ultra-low-noise internal amplifier that eliminates triboelectric cable noise and the need for an inline amplifier
- Nominal sensitivity -174 / -178 / -182 dB re 1 V/µPa (H23-080 / -100 / -130)
- Frequency response (+6/-10 dB) 5 Hz to 100 kHz / 120 kHz / 150 kHz
Applications
Calibration, military surveillance, underwater biological studies, ship noise studies, pump cavitation and machinery studies, and monitoring of underwater ordnance.
